Abstract: FIELD: mining industry.  
     SUBSTANCE: invention relates to the field of downhole seismic exploration and can be used to isolate vertically oriented physical and geological inhomogeneities of a rock mass in the near-wellbore space. When conducting downhole seismic exploration, refracted (head) waves are taken as a useful signal, time corrections are introduced for the position of the excitation point, and seismic recordings from the excitation points located in the well from the cover of the refractive formation to the surface are summed up. A total seismogram is obtained containing an amplified refracted and suppressed direct and reflected waves, on which the hodographs of the refracted wave and refracted-reflected waves formed at the vertical and sub-vertical acoustic boundaries are distinguished. Based on the comparison of the hodographs and the values of the apparent velocities, the position of the acoustic boundaries, their angle of inclination and the range of depth expansion within the interval from the surface to the refractive boundary are determined.  
     EFFECT: increase in the accuracy of localization of the desired vertical or sub-vertical boundaries, determining the position of their exit to the surface (or the projection of such an exit), determining the angle of inclination and the depth range.

Abstract: FIELD: electrical engineering.  
     SUBSTANCE: invention relates to the field of electrical engineering, in particular to a vector field-oriented control system for an electric drive based on an asynchronous motor with a short-circuited rotor. The method for forming the flux linkage of the rotor of an asynchronous motor with a short-circuited rotor as part of an electric drive with vector field-oriented control for static operation mode is that it provides the creation of a signal of a given moment M ref , by means of which the dependence of the flux linkage of the rotor on the given moment M ref  is formed to determine the value of the flux linkage of the rotor at a given moment  . At the same time, the maximum    flux linkage is calculated, which, when the stator voltage reaches the given value   , limits the value of the rotor flux linkage     at a given moment and generates a flux linkage signal ψ ref . Next, the boundary angular rotation frequency ω  Pmax  of the rotor is determined. If the angular frequency of the rotor is ω≤ω  Pmax , then a signal of a given flux linkage is formed, which corresponds to the flux linkage signal ψ ref . As soon as the angular frequency exceeds the boundary value ω>ω Pmax , a task signal is generated for the rotor flux linkage    in the power reduction zone, which is determined taking into account the value of the maximum stator voltage   . Next, the resulting signal of the specified flux linkage    of the asynchronous motor rotor is formed, the value of which at ω≤ω  Pmax  corresponds to the signal of the specified flux linkage ψ ref  for the limited voltage zone, and at ω>ω Pmax , to the value of the signal of the rotor flux linkage task    in the power reduction zone.    
     EFFECT: increase in the energy performance of an asynchronous electric drive with vector field-oriented control when operating in the area of limiting the stator voltage and in the area of high engine speeds.

Abstract: FIELD: medicine.  
     SUBSTANCE: invention relates to the field of medicine, namely orthopedic dentistry, and can be used at the initial therapeutic and diagnostic stage to achieve optimal balanced movement of the lower jaw, to prevent bite displacement in the course of complex treatment of patients with temporomandibular joint (TMJ) dysfunction. To do this, the optimal height of the lower part of the face and the therapeutic position of the lower jaw are determined by separating the dentition and kinesiological actions. Next, a kinesiography examination is performed. Then, by means of heated wax rollers, the optimal height of the bite position is determined and the desired position of the lower jaw is obtained. Then kinesiological tests start to assess the mobility of the cervical spine. The next step is to remove imprints from the first and second rollers for the manufacture of working models from a hardness class IV die stone, on which the landmarks of the labial bridles in the form of lines are applied with a marker and installed in the articulator space using a facial arc and wax rollers fixing the therapeutic position of the jaws in the articulator space. After that, plaster models of the jaws are used to make an intraoral occlusal apparatus. The resulting intraoral occlusal apparatus is stored on the dentition of the lower jaw, using articulation paper to obtain prints of occlusal contacts on the occlusal surface of the intraoral apparatus. Longitudinal front and rear occlusal tracks are created on the chewing surface of the device to obtain a front guide and a rear balancing support. The anterior and lateral parts of the surface of the intraoral occlusal apparatus are sanded. When the stabilization of occlusion and centering of the jaws on the intraoral occlusal apparatus is achieved, the blocking of movements on the side of condyle compression is eliminated, working side movements are restored, the patient adapts to the optimal height of the lower face and when restoring the function of the dental system, orthodontic or orthopedic treatment is carried out, continuing the use of the intraoral occlusal apparatus.   
     EFFECT: method provides effective treatment of musculoskeletal dysfunction of the temporomandibular joint by stabilizing the optimal position of the jaws due to the creation of a canine guide in harmonious interaction with the distal balancing on the intraoral occlusal apparatus, obtaining an occlusal diagonal with simultaneous occlusal functioning, canine sliding on the left and balancing contact on the distal buccal cusp of the second molar on the right and posterior balancing support.
